Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to a civil engineering detecting apparatus, in particular to energy and mass detecting apparatus for the underground water flow velocity mass point movement, specifically to a three-dimensional flow velocity vector, energy and mass gauge.BACKGROUND OF THE INVENTION[0002]It is known that all the infrastructure constructions of the civil engineering relate to two important influence factors, namely, the interaction of water and rock and soil. The former dynamically and actively etches the foot stone of the underground engineering construction in an ever-present way; the latter statically and passively resists and prevents the etching and damage from the former. A complete and efficient monitoring mechanism should be established in order that both of them realize peaceful coexistence and a long period of stability. For this reason, the invention proposes to establish a prediction and forecast system which is implemented to qua...

Problems solved by technology

To obtain the value in conventional methods, engineers can obtain the leakage characteristics of the individual samples through the indoor leakage experiment mainly by sampling the soil, but cannot acquire the real leakage from the in-situ status.

With the rapid advancement of the modern civil engineering construction, such experiment cannot meet the need of the production practice.

It is known that due to the defect of the “Dupuit pumping experiment theory” itself and the extremely high requirement for the experiment operators, there are fewer and fewer such experiments.

Above all, this experiment only obtains the comprehensive physical property leakage index of each sequence of the rock and soil under the artificial disturbance flow field, namely, the balance amount of rock and soil pore volume and pumping volume, but cannot obtain the leakage velocity field and vector field of the underground water in the natural flow field.

Therefore, it cannot solve many critical technology issues on leakage that the civil engineering meets.

Although the above inventions reach the requirem
